An unusually short SiSi distance of 2.518(3) Å despite an antibonding interaction between these centers and a small endocyclic angle of 67° at phosphorus, these are the surprising structural features of the title compound 1 , which forms by cyclocondensation of t BuSiFCl 2 with CyPHLi in 33% yield. The structure of 1 reflects a tug‐of‐war between the three SiPSi and the six PSiP angles, Cy = cyclohexyl.
